摘　　要：运用灰色系统理论,以农户为研究单元,以临夏北塬46个农户为研究对象,对其农业生态经济系统的产业结构与效益进行了灰色关联分析研究。结果表明,养殖业在该区域农业生态经济系统中占有最大的优势,其次为种植业、工副业;从各产业投入产出关联分析来看,种植业>养殖业>工副业>林果业,林果业才初具雏型,尚未产生效益;认为在该农业生态系统中,应在稳定粮食生产的前提下,大力发展草食家畜,改善林果业在系统中的地位,丰富工副业内部结构,从而促进农业生产总效益的提高。本研究结果对当地产业结构的优化调整及产业模式的效益评价具有较高的参考价值。In this paper, the structure and benefit of Eco-economic system in agriculture were analysed, based on the DATA from 46 households in Beiyuan(Linxia, Gansu), by means of Grey-Relation Analysis. The results indicated that, the system was dominated by livestock, and followed by plant-industry, sideline and fruited forest resp. Nowndays, the fruited forest is growing, doesnot give benefit yet. For improving the benefit of the system, it seems that some adjustments should be took for each of the subsystems, respectively, i. e., placing emphasis on livestock, as well as improving fruited forest, and enriching the elements of the sideline, on the base of stable grain prodction. It is clear, the results will be used as good consultation for adjustment & praisal to agri-production.
